🆕

Our group co-attention achieves a further performance gain (81.1 mean J on DAVIS-16 dataset), related codes have also been released.

The pre-trained model, testing and training code:

Quick Start

Testing

1. Install pytorch (version:1.0.1).

2. Download the pretrained model. Run 'test_coattention_conf.py' and change the davis dataset path, pretrainde model path and result path.

3. Run command: python test_coattention_conf.py --dataset davis --gpus 0

4. Post CRF processing code comes from: https://github.com/lucasb-eyer/pydensecrf.

The pretrained weight can be download from GoogleDrive or BaiduPan, pass code: xwup.

The segmentation results on DAVIS, FBMS and Youtube-objects can be download from DAVIS_benchmark(https://davischallenge.org/davis2016/soa_compare.html) or GoogleDrive or BaiduPan, pass code: q37f.

The youtube-objects dataset can be downloaded from here and annotation can be found here.

The FBMS dataset can be downloaded from here.

Training

1. Download all the training datasets, including MARA10K and DUT saliency datasets. Create a folder called images and put these two datasets into the folder.

2. Download the deeplabv3 model from GoogleDrive. Put it into the folder pretrained/deep_labv3.

3. Change the video path, image path and deeplabv3 path in train_iteration_conf.py. Create two txt files which store the saliency dataset name and DAVIS16 training sequences name. Change the txt path in PairwiseImg_video.py.

4. Run command: python train_iteration_conf.py --dataset davis --gpus 0,1
